Embodiment 1

[0024] The embodiment of the present invention uses the preparation method of the collection method of the whole section soil sample, the present invention discloses a kind of collection method of the whole section soil sample, comprises the following steps:

[0025] 1) Excavating and repairing the earth pit: excavating the earth pit, the earth pit has at least one vertical surface, and trimming the vertical surface of the earth pit to be perpendicular to the ground plane;

[0026] 2) Place the auxiliary wooden frame: the auxiliary wooden frame includes a hanging arm and a vertical arm perpendicular to the hanging arm; place the supporting hanging arm on the horizontal surface of the vertical surface of the pit, and ensure that the vertical arm is flat on the vertical surface of the pit. face;

[0027] 3) Make the side and bottom of the entire section of soil sample: use the collection tool to remove the soil on the left and right sides of the entire section of the soil sample...

Embodiment 2

[0033] Embodiment 2: The length of the earth pit is 170cm, the width is 140cm, and the depth is 140cm.

[0034] The width of the hanging arms perpendicular to the vertical plane of the pit is 100 cm; the width of the vertical arm parallel to the vertical plane is 30 cm.

[0035] Described collection tool comprises wide spatula, medium spatula and narrow spatula, the knife width of described wide spatula is 30cm, the knife width of described narrow spatula is 4cm, and described medium spatula is between the two; The wide spatula and the medium spatula are used to process the left and right sides of the entire section of soil sample; the narrow spatula is used to process the bottom surface of the entire section of soil sample. The use of collection tools including wide blades, medium blades and narrow blades, and the use of different tools for different areas of soil greatly improves work efficiency and reduces the probability of collapse.

[0036]In summary, the present invent...

Abstract

The invention discloses a method for collecting a whole-section soil sample. The method comprises the following steps: 1) digging a soil pit, wherein the soil pit has at least one vertical plane, and the vertical plane of the soil pit is finished to be perpendicular to the horizontal plane; 2) an auxiliary wooden frame comprises a hanging arm and a vertical arm perpendicular to the hanging arm; placing the supported hanging arm on the horizontal plane at the outer periphery of the vertical plane of the soil pit, and guaranteeing that the vertical arm is flatly attached to the vertical plane of the soil pit; 3) removing soil on the left and right sides of the whole-section soil sample labeled by the vertical arm by using a collection tool; vertically inserting along the bottom of the vertical arm by using a supporting tool; removing soil below the supporting tool by using the collection tool; 4) removing the auxiliary wooden frame, sleeving the sample collection box in the finished whole-section soil sample, taking out the supporting tool, and segmenting the back of the whole-section soil sample by using a fine line, so as to obtain the whole-section soil sample. According to the method disclosed by the invention, the production efficiency is improved, time and manual labor are saved, and the defects that the original soil sampling method is complicated and unsuitable for sandy soil are overcome.

Description

technical field [0001] The invention relates to the field of soil treatment, in particular to a method for collecting whole section soil samples. Background technique [0002] Soil is a strategic resource for human survival and rejuvenation. With the rapid development of industrialization, urbanization, and agricultural intensification, a large amount of untreated waste is transferred to the soil system, and is collected and left in the soil environment under the action of natural factors. It is estimated that the soil area polluted by pesticides and heavy metals in China amounts to tens of millions of hectares, of which 2 million hectares are polluted by mining areas 2 , about 5 million hm of oil-contaminated soil 2 , Solid waste dumping pollutes about 50,000 hm of soil 2 , has posed a serious threat to the quality of China's ecological environment, food safety and sustainable social and economic development. The types of pollutants mainly include heavy metals, nitrates...
